Differences in Mathematical Communication Skills Using Draft Pocket Books and Domino-Based Cards PMR

摘要

This study aims to find out: Differences in ability Communication skills that use pocket pocket machinesand those using PMR-based This study is a quasi-experimental study. The population of this study were students of class VII 239 TA 2017/2018. Sample selection is done by simple random samplingby randomizing the class. The instrument used consisted of: communication skills test and problem solving ability with student activity sheets. Data in this study were analyzed using descriptive statistical analysis and inferential analysis. Inferential analysis of data is carried out using the t-test. The results showed that there were differences in communication ability using a draftpocketbook and a PMR-based domino card. It is based on t-test analysis results for the model obtained t_(hitung) 3.006 and t_(tabel) 2,056 sig = 0.004. where is the value of this sig that is Criteria 0.05.
